Marigold, also known as the large cosmos, is a beautiful ornamental flower with bright colors and a long blooming period, loved by many. To grow marigolds well is not an easy task. This article will introduce you to the detailed care methods for marigolds, helping you to easily grow healthy and beautiful marigolds.
Soil SelectionMarigolds are not particular about soil, but a well-draining, highly breathable sandy soil is preferable. Before planting, it is recommended to deeply turn the soil to improve its structure and increase its fertility. Adding an appropriate amount of decomposed organic fertilizer can provide sufficient nutrients for the marigolds.
Lighting and TemperatureMarigolds enjoy sunlight and should be provided with ample light during the growing period. During the hot summer months, they should be shaded appropriately to avoid direct strong sunlight. The optimal growing temperature for marigolds is between 15-30 degrees Celsius. In winter, it is important to keep them warm and prevent frost damage.
Watering and Fertilizing1. Watering: Marigolds prefer a moist environment. During the growing period, keep the soil moist but do not overwater to avoid root rot. During the hot summer, increase watering frequency slightly to keep the soil slightly moist, and reduce watering in winter to prevent the soil from being too wet.
2. Fertilizing: Marigolds require a higher amount of fertilizer. Apply a compound fertilizer every 15-20 days during the growing period. Before flowering, you can increase the application of phosphorus and potassium fertilizers to promote blooming. After fertilizing, water promptly to prevent fertilizer burn on the leaves.
Pruning and Pest and Disease Control1. Pruning: During the growth of marigolds, it is necessary to prune withered and diseased branches to maintain a neat and beautiful appearance. Pruning can also promote the growth of new branches and enhance their ornamental value.
2. Pest and Disease Control: Marigolds are susceptible to pests such as aphids and red spiders. When pests are found, use high-efficiency and low-toxicity pesticides for control. Strengthening ventilation and maintaining a clean environment also help prevent pests and diseases.
Propagation MethodsMarigolds can be propagated by播种 (seeding) and 分株 (division).
1. Seeding: Conduct seeding in spring or autumn. Before seeding, soak the seeds for 24 hours to improve germination rates. Keep the soil moist after seeding, and with the right temperature, seeds will germinate in about 7-10 days.
2. Division: In spring or autumn, dig up vigorous marigolds and divide them into several plants, each with 2-3 buds, and replant them.
Caring for marigolds is not complicated. By mastering knowledge about soil, lighting, temperature, watering, fertilizing, pruning, and pest and disease control, you can easily grow beautiful marigolds. I hope this article is helpful to you and wish you a pleasant gardening experience!
